The freebies are nice for logging data, but, as one would expect from a freebie, aren't much good for exploring (or maybe I just haven't figured it out).
If I can be of any help, please PM me.

I have a private wiki set up on my personal server that has a database I've filled with most of the Mode 1-3 PIDs with description, data format, range, raw data to human readable form formulae (for ScanGaugeII, but should be easy to convert to any other device/app that allows custom entries), &c.
If you would like access to that, just PM me and I'll setup an acct for you. The wiki was setup just for my own use, but if you want to add your data, I will open it up to at least The370Z members, if not the Universe.
